A furtherobjectof the invention is in the v provision of'a resilient stop holder which is easily flexed formoving the stop member into i A further object of the invention is in the provision of a work stop of this kind made of easily separable parts, which may be assembled and taken apart for adjustment and re} pair with the greatest facility.

1 .A further object of the inventionis in the provision ofan'adjustable stop, in which the .stop member may be set in a variety of dif- 'ferent angular positions for engaging the work11 v a I o Other objects of the invention will appear hereinafter, the accompanying drawings illustrating a preferred embodiment of the invention;

In the drawings Figalis a side elevation of a work stopconstructed in accordance with this invention, with its stop member in engaging position. Fig. 2 is a sectional view showing the work stop in raised position; Fig. 3 is a plan view of the work stop; Fig. 4 is a perspective of the resilient member of the work stop and Fig; 5 is a perspective of the work stop operating member.

Referring more particularly to the drawings, a bed plate 6, of apunchipress or any other suitable mechanism, has a stripper plate or support 7, raised aboveit to provide a space or passageway 8, in which-the material or stock 9, ismovable, to be acted upon by the punch press or other mechanism.

The work stop comprises a stop member 10, preferablyin the form of a short bar or pin adaptedto-move freely in an opening 11, in plate 7, and into and out of position to engage the work 9 in the passageway 8.

- the connected end of the spring 14 extends.

' At its upper end, the stop member 10 is provided with opposite grooves 12, adapted to be engaged in any onelof a number of slots 13, provided in the edges or; tip of a flat spring supporting member 14, which is free at thepin supporting end, but is secured to theplate 7 at the other end, bymeans of fastening screws 15, or other suitable fastening means; Intermediatethe ends of'the springs 14 it has an off-set portion '16 raised above the upper surface of the plate 7 Anoperating member 17 has a flat por-L tion '18 at one end, adapted to engage under the raised portion l6 of the spring14, and

these portions are provided with registering perforations 19 and 20, through which a fastening, screw" 21, is inserted loosely, and threaded into the plate 7 ,for holding the spring and operating member in" position. The operating member 17 has an engaging portion 22,: connected to the flat portion 18 by parallel strengthening sides 23, but spaced therefrom at their adjacent ends, andslightly'off-set forminga slot 24, through which Any suitable means may be provided for actuating 'the operating member, such ,as represented, for example by means of an adjusting screw 25, which has a lock nut 26 for accurately holdingit in position with-respect toanactuating member 27. I

' When the stop member 10lis in its ordinary stop position, the spring 14 lies flatly against the upper side of the'plate 7, pressing the operating member "17 outwardly upon J fiat portion 18 .andraising the operating end as shown inFig. v1, The movement of the-actuating member 25 toengage the'operating member, as shown in Fig. 2, will flex the spring 14,: raising thef stop pin 10 out -of position "to-engage the-woraas shown in 'Fig.2.' The resilience of the ,spring114 returns the parts and the pin-10 to normal stop position as soon" as the actuating member operating member.

too,

. ing screws 15, so that the screws may be inserted and removed through openings 28. With this construction it is obvious that the stop member 10 may be set in different angular positions at the end of the spring; that the stop is easily attached and removed; that parts are simple in'construction, easily applied and removed; andthat the movement of the operating member will flex the spring, and cause the movement of the stop pin.

I claim:

1. A work stop comprising a resilient member attached at one end, a stop member at the other end, 'and operating means engaging the resilient member intermediate its ends and adapted to 'flex the free end of the resilient member to move the stop member.

'2. A work stop comprising a flat spring member attaohedat one end, and slotted at the other, a stop member having opposite grooves adapting it to engage the slotted member, and a :rocking operating member engaging the spring member intermediate its ends and movable to raise and lower the stop member.

3. A Work mop comprising a flatspring attached at one end and free at theother, a stop :member attached, to the free end, an intermediate ofl'set portion, and an operatin member having a portion seated in the set portion and a projecting portion to rock the seated portion thereby flexing the spring and moving the stop member.

4. In a work stop, a flatspring having an intermediate portion offset from the ends, means for attachingone endof the spring to a support, the other end being free, a stop mem er at the free end, and operatingmeans having a flat portion adapted to be seated in the offset and a portion extending at an angle therefrom and movable to flex the spring and correspondingly vmove the stop member.

:5. Ina work stop, a resilient member fixed at one end and free at the other, the free end having slots at different angles therein, a stop member having opposite grooves adapting it to be seated in any one of the slots, and operating means to engage and flex ghee resilient member to move the stop mem- I,

, *6. A work stop comprising a flat spring ofiset intermediate its ends, one end being fixed-andthe' other free,.a-stop memberat the free-end, and operating means having a flat portion engaged by the offset in the spring with an operating portion extending at an angle therefrom-and adapted to rock the said flat portion to "flex the spring and correspondingly move the stop member. a 7 (I. A work/stop-comprising a-resilient mem- .ber,-a stop member at one end, operating means having a slot through which the resilient member is inserted, the under end enber, and the other endoverlying the attached end ,of the resilient member and having openings through which the attaching means may be actuated without separating the parts.

. -9. A work stop eomprising'a fiat spring with-an intermediate offset, fastening means at one endfor securing it to aflatsupport with the'other end free to move, a removable stop pin at the free end, an operating mem-- her having a flat portion at one end ada ted to be seated below the offset portion 0 the spring and'against the springsupport, the

operating .member having an engageable portion extending upwardly'fromthe flat portion and separated. therefrom by a slot through which the spring extends, the said portions of the operating member being connected at the sides by angular strengthening portions.

10. A work stop comprising a flat spring attached at one end and free at the other, a stop member at the free end,'an operating member having a slot through which the spring extends, one end being positioned below theintermediate portion of the spring and the other end extending outwardly therefrom and adapted to flex the spring and movevthe stop, the spring and the operating member having corresponding openings through the engaging intermediate and end portions respectively, and a fastening member insertable therethrough for holding the spring and operatlng members together and limiting their relative movement.
